Q&A: Diagnosing Salinity Spikes The figure above shows a time series of salinity from a moored CTD. For most of the deployment, salinity showed frequent downward spikes, dropping from an expected range of 18-26 psu to near zero. Can you determine the cause?...
November 2019 Newsletter The data above come from a profiling CTD, deployed in sea conditions that caused approximately 1-meter ship heave. Two things stick out – relatively unchanging salinity data during the downcast, and noisy data during the upcast (shown in light...
The figure above originates from a single Shallow SeaFET V2 pH sensor, which produces two pH values (Internal pH and External pH) from two separate reference sensors. The black X’s indicate pH validation samples. While environmental conditions affect each the...
November 2018 Newsletter The figure above originated from an SBE 37-SMP MicroCAT moored CTD deployed in shallow seawater. On day 38, the salinity data appears to jump from a near-zero value, steadily increasing until around day 43, where it stayed around 30psu. Nearby...
These data show a subtle problem that is producing “fuzzy” salinity and oxygen data. While the overall shape of the profile appears reasonable, small spikes are present throughout the CTD cast. The black lines encompass a particularly strange spot where both salinity...
We hope to see you at UG2 '24 We are excited to sponsor the upcoming 2024 Glider Workshop in Ann Arbor, Michigan, from September 10 - 12, 2024. Overview This workshop will bring together the global underwater glider community to strengthen international collaboration...
